pip,代理验证和“不支持的代理方案"; [英] pip, proxy authentication and "Not supported proxy scheme"
问题描述
尝试在新的python安装上安装pip.我陷入代理错误.看起来像是get-pip
或urllib3
??
Trying to install pip on a new python installation. I am stuck with proxy errors. Looks like a bug in get-pip
or urllib3
??
问题是我是否必须经历如下所述设置 CNTLM的痛苦还是有捷径?
Question is do I have to go through the pain of setting up CNTLM as described here or is there a shortcut?
get-pip.py文档表示使用--proxy="[user:passwd@]proxy.server:port"
选项指定代理和相关身份验证.但是似乎pip传递了整个内容,因为urllib3
会将"myusr"解释为url方案,因为:"我猜是(?).
get-pip.py documentation says use --proxy="[user:passwd@]proxy.server:port"
option to specify proxy and relevant authentication. But seems like pip passes on the whole thing as it is to urllib3
which interprets "myusr" as the url scheme, because of the ':' I guess (?).

当我在不使用usrname和密码的情况下运行命令时,它可以正常工作,但是代理拒绝该请求,要求其进行身份验证("407身份验证要求").
When I run the command without the usrname and password it works fine, but proxy rejects the request saying it needs authentication ("407 authenticationrequired").

我简要介绍了 urllib3\poolmanager.py
和似乎与用户名/密码无关.
I had a brief look at urllib3\poolmanager.py
and it doesn't seem to have anything to do with username/passwords.
推荐答案
这是在抱怨URL的方案(urlparse
理解为myusr
),要解决此问题,您应该这样做:
This is complaining about the scheme for the URL (which urlparse
is understanding to be myusr
), to work around that you should instead be doing:
get-pip.py --proxy http://myusr:mypswd@111.222.333.444:80
